This research was conducted to analyze flavonoids in juice and to investigate correlation between 60 germplasms of satsuma mandarin (Citrus unshiu Marc.) on the basis of the result of flavonoid analysis. Juice of satsuma mandarin contained 6 flavonoids, 2 flavanones such as narirutin and hesperidin, 1 flavone such as rutin and 3 polymethoxylated flavones such as sinensetin, tangeretin and nobiletin. Hesperidin content ranged from 41 to 196 mg/L. Narirutin content ranged from 25 to 230 mg/L. The average of rutin content was 2.2 mg/L but it was not detected in some cultivars. Polymethoxylated flavone which is known as a citrus specific flavonoid, was detected in all germplasms in small quantities. Cluster analysis using R program (Version 3.1.1) was carried out with the results of the flavonoid analysis and harvesting time of satsuma mandarin germplasms. All germplasms were grouped as A, B1 or B2. But all 3 groups contained very early-ripening type, early-ripening type and commonly-ripening type cultivars. This showed there was no correlation between flavonoids in juce and their harvest time.

Rhizomes of Acorus gramineus Soland have been used as sedatives, analgesics, and stomachics in Korean medicine. Even though A. gramineus produced in Korea is known as having better efficacy of a remedy than that in China, its cultivation area has not increased because of the lack of seedlings. To solve this problem, seed propagation method was tested. Seeds were harvested and sowed three times in June, 2005. The best results showed at greenish yellow seed stage harvested in mid June, and its germination ratio was 90.7%. Seeds were well stored at $5^{\circ}C$ for 30 days. As for in vitro culture, multiple shoots were induced first in MS basal medium supplemented with $2.0mg{\cdot}L^{-1}$ NAA plus $0.1mg{\cdot}L^{-1}$ BA, and then roots were induced in MS basal medium containing $0.1mg{\cdot}L^{-1}$ BA or $0.5mg{\cdot}L^{-1}$ NAA plus $1.0mg{\cdot}L^{-1}$ BA. Growth of A. gramineus seedlings in Wonyesangto, potting material sold in markets for horticultural plants, was superior to vermiculite.

The purpose of this study was to identify the effects of tensor fasciae latae-iliotibial band (TFL-ITB) self-stretching exercise on the lumbopelvic movement patterns during active prone hip lateral rotation (HLR) in subjects with lumbar extension rotation syndrome accompanying TFL-ITB shortness. Eleven subjects (9 male and 2 female) were recruited for the two-week study. A three dimensional ultrasonic motion analysis system was used to measure the lumbopelvic movement patterns. The TFL-ITB length was measured using the modified Ober's test and was expressed as the hip horizontal adduction angle. The subjects were instructed how to perform TFL-ITB self-stretching exercise program at home. A paired t-test was performed to determine the significant difference in the angle of lumbopelvic rotation, movement onset time of lumbopelvic rotation, TFL-ITB length, and LBP intensity before and after the two-week period of performing the TFL-ITB self-stretching exercise. The results showed that after the intervention, the lumbopelvic rotation angle decreased significantly (p<.05), the movement onset time reduced significantly (p<.05), and LBP intensity decreased slightly but not significantly (p=.07). The hip horizontal adduction angle increased significantly (p<.05) after the intervention. These findings indicate that TFL-ITB stretching exercise increased TFL-ITB length, decreased lumbopelvic rotation angle, and delayed the movement onset time of lumbopelvic rotation after two-weeks. In conclusion, the TFL-ITB self-stretching exercise performed over a period of two weeks may be an effective approach for patients with lumbar extension rotation syndrome accompanying TFL-ITB shortness.

In the coming age of information warfare, information security patterns take on a more offensive than defensive stance. It is necessary to develop an active form of offensive approach to security protection in order to guard vital information infrastructures and thwart hackers. Information security products need to support an automatic response facility without human intervention in order to minimize damage to the attacked system and cope with the intrusion immediately. This paper presents an automatic intrusion response model which is developed on a Self-Extension Monitoring. It also proposes an ARTEMIS(Advanced Realtime Emergency Management and Intruder Identification System), which is designed and implemented based on the suggested model. The Self-Extension Monitoring using self-protection and replication minimizes spatial limitations on collection of monitoring information and intruder tracing. It enhances the accuracy of intrusion detection and tracing.

The previous researches about knowledge sharing were proceeded in terms of KMS (Knowledge Management System) in center. However, knowledge sharing is recently applied to Internet space, which is open to every users, as well as KMS, which is qualified for restricted people. For example, some portal sites, such as Naver, the most popular portal in Korea, have virtual spaces to share users' knowledges and it is common that many users use the spaces. Knowledge sharing online, compared with KMS, will be more advanced to promote intention for knowledge sharing because of the character of Internet space that is open to all users. Nevertheless, there are few researches about knowledge sharing in the Internet. Considering this situation, this study is attempted to figure out the factors to promote Internet knowledge sharing, based on social capital theory and self-expression concept. A survey of experienced Internet user and PLS (Partial Least Square) were utilized for analysis. The test of this study reveals that social capital and self-expression are significant factors to influence knowledge sharing intention, and that also personal innovation and self-efficacy are significantly related to the self-expression. However, personal innovation does not have significant impact on social capital. According to the result, self-expression, as well as trust and system itself, has significantly effect on knowledge sharing intention in order to promote knowledge sharing in the Internet.
